\SVEN WERNER WALLIN/ GEORG t ANSELLM WESSEN 'BY MQ I ATTORNEY PatentedJune 9, 1936 UNITED STATES PATENT OFFICE CAMP BEDSTEAD Application July24, 1934,- Serial No. 736,642 In Sweden August 16, 1933 8 Claims.

The camp bedsteads hitherto sold on the market have many drawbacks. Sofor instance they 7 have a relatively high weight and require much spaceafter folding, and therefore they are very diflicult to bring along.

The present invention relates to a folding bedstead, which maybe takento pieces and which is so constructed that the above mentioned drawbacksare overcome. Furthermore the weight of the bedstead is as little aspossible and the space required by the bedstead when folded is veryinconsiderable.

The bedstead according to the invention comprises two side frame pieceshaving tubular or U- shaped cross section and extending in thelongitudinal direction of the bedstead. Each of the said frame piecesconsists of one or more parts and between the said frame pieces isdisposed the bottom of the bedstead and two or more stirrup- 20 orU-shaped cross pieces detachably connecting the side frame pieces, therebeing'legs upon said cross pieces forming the legs of the bedstead while.ihe free end portions of the said cross pieces are shaped as pinsextending intoholes provided in the side frame pieces, the portionconnecting the legs being adapted to constitute support against theground. The especially new and characterizing feature of the inventionconsists in that the legs of each cross piece are pivotally secured inthe portion connecting the same and swingable about horizontal axes inthe plane of the cross piece and that the legs and the connectingportion are arranged in such manner that after the bedstead has beentaken to pieces all of the cross pieces or most of them may be put intothe side frame pieces or into the parts forming the same.

The accompanying drawings illustrate an embodiment of a bedstead madeaccording to the invention.

Figure 1 shows a plan view of the bedstead, the bottom of the bedsteadbeing removed in part,

Figure 2 is a lateral view of the same,

Figure 3 shows a. fragmentary section taken on line 33 of a part ofFigure 2,

Figure 4 showing the bedstead gether in a bag, I

Figure 5 shows a cross piece,

Figure 6 is a section taken on line 66 of Figure 5, and 0 Figure 7 is asection taken on line 1-1 of Figure 5.

The two last mentioned figures are drawn to a larger scale than Figure5.

Each of the side frame pieces of the bedstead consists of two tubes Hand I2, which are conwhen put tonected with each other by means of thehingeshaped joint 13. The side frame pieces are connected with eachother by means of three stirrup-shaped or concave-sectioned cross piecesl6, I7, l8, the free end portions of which are inserted in holes, whichhave been provided in the tubes 1! and I2. The free end portions of thetubes II are bent somewhat inwards and upwards and asupport M for thehead is arrangedin the said end portions. The body. rest or supportingbottom l5-of the bedstead consists of a cloth, and'the longitudinalsides of the same are provided with tubular hems, in which are insertedthe side frame pieces and the portions of the support for the head,which are connected with the tubes II.

In the cross piece, which is shown more particularly in Figure 5, .theportion l8 connecting the legs I6, I! has U-shaped cross section. Thelegs, which also have U-shaped cross section, are each pivotally securedto its end portion of the portion l8 and are pivotally disposed in thesymmetry plane of thecross piece. Abrace l9 whichconsists preferably ofa tube, has one end pivotally connected to the leg I! at a distance fromthe free end of the latter. The other end is slidable in the portion! 8.In a corresponding way a brace is .providedat the leg 16. This brace,however, consists of two parts 20 and 2| pivotally connected with eachother, and the freeend of the part 2| is slidable in themember [8. Aspiral spring 22 is disposed in the middle of the member l8, againstwhich spring the braces rest, when the legs of the cross piece areconnected with the side frame pieces and when the cloth or fabricforming the body rest .or bottom of the bedstead has been strained. Asmentioned the legs l6 and I! have U-shaped cross sections, in order thatthe braces, which are narrower than the distance between the flanges ofthe legs, may be foldedinto the same, the two legs in disassembledcondition of thebedstead folding down into alignment with the crosspiece member and extending from the ends thereof. The spring 22 issecured to the member 18 by means of a rivet 23, which is dis,- posed ina plate 24 soldered on to the member l8.

On setting up the bedstead the side frame pieces are introduced into thetubular hems of the bot.- tom l5 of' the bedstead. After that the legsof the support for the head are inserted in the fore ends of the tubularhems and in the fore parts of the tubes ll, afterv which the bottom ofthe bedstead is strained around the member connecting the legs of thesupport for the head by means of the straining device 25. V The endportions .of the cross piece legs I6, ll, the said end portions be.-

ing formed as pins, are then introduced into the holes of the tubes ll,[2, the cloth; l5, after the 7 cross pieces have been applied assumingthe position indicatedin iull lines in Figure'5. By the brace, whichconsists" of the parts 20 and 2 I being pressed down to thepositionindicated by dash and dot lines, the cloth is strained and assumes theposition indicated by dash and dot lines.

' The free ends of the braces then rest against the for the head and thetubes J I is swung upwards in the direction'of the arrow in Figure 2 andis spring 22, whichresults in the cross piece becom ing very steady. Theend portionlli' of the part 20, which forms the joint-together with thepart 2|, is U-shaped and extends past the said joint and willthus serveas a stop against the part 2| in the pressed down positionfso as toprevent; the brace fromjbeing pressed down too .much.

The spiral spring serves to prevent, the cloth from V burstingwhensubjected to hard stresses, the rbraces pressing the spring togetheralittle on such, occasions. V

The bracesZO, 2 Iare(Fig.5) and the cross'pieces and the support for thehead are removed,The legs '20 and 2| are ,swungdow n in line with thepmember [8, whichconnects the legs, and the braces are folded into theflegs and themember l8 to the position which dsindicated in dashand dot.lines'inFigure 5.

Thereafter "each cross piece is pushed into any 7 oi? the'tubes'l'l andl2, the latter thusforming hollow, elongated cro'ss piece storagemembers which could be any other practical form rendering them-capableof receiving the crosspieces in collapsed condition of the bedstead. Thesupport for'the head also is inserted in a similar way. The foldedsideuf rame pieces are then rolled towards each other and a very smallpackage is obtained, whichmay be inserted n a covering in the shape of abag; The bedstead when putfinw a bag "is illustrated iniFigure 4. V c 7.[By the side frame pieces being provided with thejoint l3r-it ispossible to fold the bedstead without, removing thebottom ii of thebedsteadfrom the side frame pieces.

A similarguiding is also obtained, if the free flanges of the connectingpmemberl8 are provided with inwardly and V downwardly bent edges.

Figure 7 shows asection taken on line 1f1 oi? 'Figure5, the -leg I9,however, imagined to be swung down to the position which is indicated bydash and dot lines to the right in Figure 5. Furs ther, the cross pieceis imagined to be disposed in one of the'tubes forming, the side framepieces, 'for example the tube l2.

g Thespiral. spring 22 may also be, replaced by another member servingas a stop, especially in V bedsteads that are'not meant to be subjectedto {too hard stresses. i'urthermore it is not necessary to provide thetubes l I and I2 with thejoints V r 13, but they maybe connected bymeans of sleeves.
